toBeWide

Deprecated

Prefer toHaveAttrs which checks multiple attributes at once:

expect(term.cell(0, 0)).toHaveAttrs({ wide: true })

Assert that a cell contains a double-width (wide) character, such as CJK characters or certain emoji.

Signature

expect(cell).toBeWide()

Usage

// CJK character occupies two columns
expect(term.cell(0, 0)).toBeWide()

// ASCII characters are not wide
expect(term.cell(0, 0)).not.toBeWide()

Accepts

Region	Supported
term.cell(r, c)	Yes
term.screen	No
term.row(n)	No

Notes

• Wide characters occupy two terminal columns
• The first cell of a wide character has toBeWide() true; the second cell is a continuation cell
• Common wide characters: CJK ideographs, fullwidth forms, some emoji
